LeCun is reasonable, like a lot of researchers, and was a while back (in a way) perplexed that people are finding uses for these text predictions at all considering they're not really perfect. I'm not exactly ascribing bad faith to all of these people, but for Hinton and the fact that he went on a media tour basically, I don't see how that could be in good faith. Or even logical, to continue with his work, if there's some probable X-risk.
But what I do know is that it is in the interests of these companies to press the fear button. It's pure regulatory capture and great marketing.
Personally: it's tiring when we have AI-philosophy bros hitting home runs like "what if we're actually all just language predictors." Coupled with the incessant bullshit from the less wrong-rationalist-effective altruist-crypto grifter-San Francisco sex cult adjacent about how, ackshually, AGI is just around the corner and it will take your job, launch the nukes, mail anthrax to you and kill your dog.
People approximated text prediction. It got good at it. It's getting better at it. Will it be AGI? Could it be construed as AGI? Can we define AGI? Is there existential risk? Are we anthropomorphizing it?
My take is: no, no, no, depends and yes. For whatever a take is worth.
